Laserdisc only ever played second fiddle to VHS. (And it did last over 20 years!) Some movies were "new" releases when the LD came out, but are "old" catalog titles now, and studios often don't think they could sell enough copies to make a profit. Look how long it took for Howard the Duck to come out!
It will be interesting to see what Warner's new "burn on demand" program shakes loose from the vaults!
